Caterpillar C32 ACERT Marine Diesel Engine Heat Exchanger Plates, Gaskets & Seals

OEM-grade plate packs, gaskets, seals & hardware for CAT C32 ACERT marine propulsion—engineered for reliability, corrosion resistance, and fast turnaround.

CAT C32 ACERT Heat Exchanger Gaskets, Plates & Seals

The CAT C32 ACERT is a 32.1-liter V-12 marine diesel designed for high-output applications—sportfishers, motor yachts, and commercial workboats. To hold temperature under heavy load, the C32 ACERT uses a closed-loop jacket-water circuit cooled by a seawater heat exchanger (often titanium plate construction). MechPro supplies complete plate packs, gasket sets, O-rings, spacers, bolts, collars, and covers for C32 ACERT variants (including recreational Tier 3 ratings). Provide your engine serial number (ESN) for an exact part match.

Product Overview

Heat Exchanger Gaskets
Create a tight, leak-free seal between exchanger plates. Essential for efficient operation and fluid isolation.

Heat Exchanger Plates
Precision-engineered titanium plates maximize heat transfer efficiency, ensuring consistent cooling for C32 ACERT engines.

Heat Exchanger Seals
Durable elastomeric seals prevent leaks at joints and maintain proper pressure within the system.

Together, these components sustain optimal engine cooling performance, prevent overheating, and extend engine life.

How the C32 ACERT Heat Exchanger Works

  • Jacket water (engine coolant) circulates through one side of the plate stack.
  • Seawater flows through the opposite side, absorbing heat and discharging overboard.
  • Fluids never mix, protecting the engine from corrosion while holding optimal temperature for power and efficiency.

Benefits: prevents overheating, stabilizes combustion temps, extends engine life, simplifies service.

Maintenance Tips (MechPro Best Practices)

  • Inspect/clean plates every ~1,000 hours or annually (sooner in heavy seawater scale).
  • Replace gaskets at each teardown—don’t reuse.
  • Freshwater-flush seawater side after extended operation; check raw-water pump impeller and discharge flow.
  • Verify tie-bolt torque per spec after thermal cycles (where applicable).

Frequently Asked Questions (FAQs)

Q: What vessels typically use the C32 ACERT?

A: High-performance sportfishing yachts, large motor yachts, fast patrol/workboats, and commercial craft needing 1,600–1,900+ bhp continuous reliability.

Q: How often should the C32 ACERT plate stack be serviced?

A:  Clean/inspect about every 1,000 hours (or seasonally). Replace gaskets each disassembly; replace plates when pitted, thinned, or warped beyond tolerance.

Q: Can MechPro match parts for different C32 ACERT ratings and coolers (SCAC/SWAC)?

A:  Yes. With your ESN (and cooler photos), we’ll confirm the correct plate metallurgy, gasket compound, and hardware for your exact arrangement.

Q: Do most Caterpillar C32 ACERT Marine Diesel Engines use a shell and tube heat exchanger or a plate heat exchanger?

A: Most Caterpillar C32 ACERT marine engines use either a plate heat exchanger or a shell and tube heat exchanger, depending on the specific configuration. Options for a plate heat exchanger are available for the primary cooling system, often highlighted as a key feature for efficiency, and configurations using shell and tube exchangers for both the jacket water and the aftercooling circuits are also offered.

  • Plate Heat Exchangers: These are commonly used in the heat-exchanged (HEX) cooling system and are praised for their efficiency, as seen in the description of a titanium plate-type heat exchanger used to regulate engine temperature with raw seawater.

  • Shell and Tube Heat Exchangers: These are used in some configurations for both the jacket water and the separate circuit after-cooling (SCAC) systems.
  • Cooling System Options: The choice between heat exchanger or keel-cooled options is available on many C32 models, but for heat exchanger configurations, the system can be a mix of plate and shell and tube types depending on the specific engine variant
